Benefit from efficient, repeatable results in cast-iron turning thanks to the combination of a CVD-coated carbide grade T505 and a double-sided chipbreaker that stabilises cutting conditions and reduces downtime; order the insert directly via Metav Werkzeuge or ask the consultants for compatibility advice.

TNMG 160412 T505 triangular turning insert — CVD-coated carbide for cast-iron turning by Tungaloy

The TNMG160412 T505 is an ISO-standard triangular indexable insert for external and internal turning, designed for economical machining of cast iron and compatible with ISO holders when matched by form and tolerance

• CVD-coated carbide grade T505 for cast iron
• Triangular ISO form TNMG with 60° included angle
• Cylindrical hole and double-sided chipbreaker
• 4.76 mm thickness for stable clamping

Faster, more economical machining of cast iron with controlled chip formation

The combination of a CVD-coated carbide substrate and the T505 grade prioritises economic performance when machining cast iron. The coating increases abrasive resistance while the carbide core maintains edge stability, which together extend tool life and reduce changeover frequency. Built-in chip control on both faces helps maintain consistent cutting forces; this reduces vibration and allows higher effective feed rates without sacrificing surface finish. For operations where cycle time and predictable tool life are decisive, this insert supports a measurable productivity advantage.

Reliable fit and handling that simplify setup and reduce errors

Produced to ISO dimensions, the insert has a triangular shape with a 60° included angle and a 0° clearance angle, ensuring compatibility with standard TNMG holders when matched for size and thickness. The cylindrical hole and 4.76 mm plate thickness ensure secure clamping and repeatable seating, which cuts setup time and minimises misalignment risks. Clear design features make it straightforward to select a matching seat and screw; the standard form also eases stock management in mixed-holder environments.

Practical cutting data and consequence for the process

A corner radius of 1.2 mm gives a balance between edge strength and surface finish, permitting moderate to heavy cutting without premature chipping. The double-sided chipbreaker supports intermittent cuts and varying stability conditions, while the carbide construction copes with typical cast-iron abrasiveness. When combined with an appropriately rated holder and stable workholding, the insert contributes to a shortened total processing time and a lower cost per component, making it a good choice for batch and serial turning where repeatable results matter.

FAQ

What materials is this insert suitable for?
The TNMG160412 T505 insert is formulated for cast iron machining and performs best when the material and cutting data match the grade’s intended use.

How does the T505 grade affect tool life?
Tungaloy’s T505 grade combines a wear-resistant coating with a stable carbide body to improve edge life under abrasive cast-iron conditions, which often leads to fewer insert changes.

Is the insert reversible and what does double-sided chipbreaker mean?
Yes — the TNMG geometry is double-sided, so both faces can be used; the chipbreaker on each face is shaped to control chips in varying cutting scenarios.

Which holder details must be checked for compatibility?
Compatibility depends on insert form, free/clearance angle, tolerance class, mounting method, size and thickness; verify the seat matches the TNMG160412 dimensions before use.
